MECHANISM non surrizrme FOIL.

Application filed March 31, 1923.. Serial No..t29,051.

To all whom it may concern: I Be it known that we, EDWIN 'J, OONLEY,

of New York, county ancl State of New York, and EDWARD J. 'VVHALEN', a citiz'enof the-- United. States, a resident of Howard Beach, in the county of Queens and State'o-f NewYork, have invented a .certain newand; useful Mechanism for Supplying F il, of"

. roll of foil l mounted; upon suitable reel,-

and the-endof the foil iscausedto pass? around rollerst 2 and 13, the, former be which the following is a specification.

This invention relates "to mechanism for supplying foil, and more particularly to mechanism for unwinding foil'from a reel and supplying it topackages to be wrapped Withsevered sheets'of foil. A I =l l11s application lsja cont nuation in par ofour original application's, Serial No. 556,952, machlne for wrapplngand sealingmetal foil, and Serial No. 613,234, machine and method for fo-rming sealed foil packages. In the .accompanying drawings, which form part of this specification, there are shownpo-rtions of the original machinesillustrating the manner in which the foil feeding mechanism is connected to the pack" age wr-apping mechanism. Two I forms of 1 I v ls'mounted ad acent roller 6 to'keep the foil mechanisms for supplying foil are shown.

Figures 1 to 5 inclusive illustrate one form' of foil supplying mechanism as illustrated in the first mentioned application, and the remaining figures illustrate another form r Of foil supplying mechanism'as illustrated t e second. above mentioned application;

In the drawings I a Figure 1 shows a supplyingmechanism, this figure,as wellas others, showing therelation of said mechanism to the'wrapping mechanism, as well fromla'shaft 15,iwhich isthe main driving shaftof the wrapping machine as well as the as some of the other figures l Figure Qshows a plan view of the mechanism. Figure 3. shows a side view of the mechanism, on the side opposite to that of Fig- Figure-.4 is a side view somewhatsimilar to t'hat of Figure l'but with certain parts in section for 'thetpunpose of illustrating in a. general way the; principal operating mechanisms and the manner in which the foil supplying mechanism is adjusted-with respect to the wrapping machine.

ing over the roller 3, passes over a roller 4; ournaled for movement in a long s1ot5, and

thence. passes over another driven roller or a i 1 cylinder 6. y The rollert is mounted for retati'on with pinions. which respectively en? gage two racks 7 and 8 on opposite-sides of said roller and which travel in closecontact with guides to prevent "lateral movements. An adjustable roller or cylinder 9, covered with some yieldable material such as rubber,

the wrapping machine illustrated in connection with the foil supplying. mechanism. The foil is severed periodically-by 'kn'ives, one of which is stationary-as shown at '10, andtheother, denoted by 11, is movable and attached to a rod 12 which is actuated by a crank 13, whose otherend has a roller engaging a cam mounted upon a shaft 141-,w'h1ch is'driven by suitable gearing foil supplying/mechanism. Thefoil is severedjust at the moment when the advancing ,plng machine,'makes contact with it; The,

foil is also fed forwardly in such a manner that the package contacts with the exact 7 .center of the foil sheetwhen severed.

'27 traveling in a camway 28 mounted on the driving shaft 15. The bell crank is mounted This foil supplying or feeding mechanism is arrangedto maintain the advancing foil sheet correctly centered and free from wrinkles, that is, in a fairly taut and extended condition. The fixed motion of the oscillating roller 4 in the guideway prevents any lateral movement of the roller or of the advancing foil. The foil from the reel 1 is unwound at a uniform rate without too great 'a'speed and it is carefully timed with respect to the intermittent rotation'of the roller 6. The means for driving the roller 3 comprises a gear. 30, a sprocket chain 31, a gear 32, a sprocket chain 33, and a gear 34 mounted on a shaft 35 which is driven from the shaft 15 by a connecting means such a's 'a chain 36 traveling around a gear 37 geared on said shaft 15;] g

' '[t is at all times necessary to keep the foil smooth and to prevent wrinkling it by reason ofiits swift passage through the machines. 'ilcc'ordm'gly there has beenprovided an oscillating roller such as 4, which maintains the foil in a well centered and in an extended condition at all times. Owing to the fact that the roller 4 is provided at bothits ends with pinions which travel in racks and, between guides snugly fitting thereagainst, no irregularity of motion such as an uneven tilting or a sidewise motion is possible. lVhen the foil is cut, that portion of it being cut is for the moment at rest.'

The soft roller 9 covered with rubber maintains the foil in a smooth condition during its downward course and prevents any sidek wise shifting of the foil. The severed sheet of foil is, of course, unsupported through the guideway 16 and would drop if it were not for the immediate advance of the package which is regularly supplied by an advancing plunger, and is able to occupy its proper position by virtue of means described in the aforesaid application.

In the second embodiment of the invention illustrated in Figures 6 and 7, which have been taken from the above mentioned application, there is shown a mechanism for supplying foil which is generally similar to the mechanism above described, but which differstherefrom in certain details. A roll of tin foil 40 is mounted upon a reel supported by ashaft 41 and the reel is friction-held by spring 42 whose object is to prevent the reel from unwinding too fast or in an irregular manner. The foil unwound from the reel passes between two 1-011 ers 43 and 44 to an oscillating roller 45 which. serves to weight the advancing foil sheet down in order to keep it in an extended smooth, and taut condition. The foil sheet thence passes over a roller 46 and down between this roller and anotherroller 47, which may be covered with a soft material like rubber. The foil sheet is delivered in a vertical position into a guideway 48, preferably shaped as illustrated, and it is severed by suitable knives or cutters 49 and 50, the latter being pivoted at 51 and the former being stationary. The roller 44 is constantly driven. i i I The power for driving the foil feeding mechanism is derived from a shaft 52 which is connected by a chain to a suitablepower.

shaft. On said shaft'52 i's mounted a cam 53 which cooperates with aroller 54 on a pivoted arm 55, receiving in its upper end, which is slotted, a link 56 attached to a plate 57 which carries a pawl 58, engaging a ratchet wheel 59, mounted upon a shaft 60. 7

On this shaft is mounted a gear 61 which meshes with a pinion 62, whereby an intermittent drive is imparted to the rollers 46 and 47 thus intermittently feeding forward the foil sheet. The foil travels continuously from the reel mounted on the shaft 41, and therefore the oscillating roller 45 moves up and down becauseof the periodic stoppage of the roller 46. During this up and down motion the roller 45 is caused to move with great regularity and exactness in order to prevent any sidewis'e shifting of the foil or any unevenness in its surface, or any tilting of the roller. This is accomplished by providing pinions 63 and 64, at the ends of the. roller 45, these pinions traveling over fixed racks 65 and 66.

The knives 49 and 50 are operated from a cam 67 on the shaft 52, which cam cooperates with a roller 68 on a bell crank 69, to the upper end of which is attached a movable shear link of the aforesaid knives. This shearcloses when the'cam is in'a certain part of its revolution and thereby severs the foil.

The guideway 48 is tapered as shown and vertically beneath it is a slot in the surface or bed of the main frame upon which the foil feeding mechanism rests, this slot being designated 7 O. The forward edge thereof is curved as shown so that the foil will not be ruptured "or wrinkled, and the lower edges ofthe guideway are also curved. The foil is unsupported immediately after being cut, but is immediately pushed forward by the advancing package, and, therefore, does not have time to drop.

The reel upon which the foil 40 is mounted "disarranged.

ers43'and 47 are covered with rubber and "are of thesame'diameter, whilethe rollers-44 and 46s are ofrmetal and are of the same diameter. The compensating roller 45 is rub-1 ber covered and its axis is always parallel with the axes of the feedingrollers, its function being to take up the slackbetween intermittent feeds. The bearingsof the roller 43, n

which are adjustable, are adjusted to make the foil feed evenly and pass over the m1ddleof the roller. The foil must be properly positioned so that when it arrives in the to the package, and for this purpose the reel guideway 48 it willlbecenteredwith respect maybe adjusted in position,after which ad justment the'constantly running rollers Wlll prevent the foil from moving sidewise, which operation is assisted by the roller 45.

The, shaft 52 may be connected to a clutch mechanismwhich is constructed to throw the shaft out of operation whenever it is desired to stop the feeding of the foil, and such construction is described in the aforesaid original application.
